1. 打开新的窗口并传送参数: 4C/8hsn

传送参数: ](0Vm_es
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") x#0C+cU

接收参数: >V(2Ke Y
string a = Request.QueryString("id"); )
Q=G&
string b = Request.QueryString("id1"); GxZQ{

2.为按钮添加对话框 LbR/it'}
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); [Pp#l*
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") !E_uQ?/w]Z

3.删除表格选定记录 ~DZ;l/&Mz7
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; p2~Q
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() &SN$D5U'

8.关于日期格式 OX`n`+^D
6+u'Tcb
日期格式设定 d$TW](Bby
DataFormatString="{0:yyyy-MM-dd}" ~JNuy"8

我觉得应该在itembound事件中 jFXU
xf
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Na6z,TW

9.获取错误信息并到指定页面 -0X> y
)mPlB.
不要使用Response.Redirect,而应该使用Server.Transfer z )pV$
I7~|!d6
e.g l =yHx\
// in global.asax 9A_7:V]_
protected void Application_Error(Object sender, EventArgs e) { /)I9+s#q9o
if (Server.GetLastError() is HttpUnhandledException) E&+^H
on
Server.Transfer("MyErrorPage.aspx"); 6-=_i)kzq
}gW}Vr <
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 7asq]Y}<
} 'MUrszOO.e
qc6IH9i`
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 %yMzgk[u

10.清空Cookie *02( J
